,employed, but that herein shown comprises and-crosswise of cuts- Any s'table 'cutting mechanismmay be l a knife-carrier 11, carryig a knifecoperat- 'ingwith form A, as shown in Fig 1. This carrier'is connectedby a linkv 1-2 and arm 13 with avhollo'w shaft 14:, to wliiehthe arm 13l is rigidly iixed At its upper end shaft 14.

carries a beveled gear 15, keyed tosaid shaft, so `that the latter canmove endwise through f said gear. Gear 15, is driveny b a gear 16 on ashaft 17, the latter driven t ough a belt (not shown) engaging a ulle18.4 The p'ulley 18 is one member oi a cliiteh, the other `member 1.9 ofwhich is controlled by -a lever `20, so that'the wheel18 canbe-connected with and disconnected [rom shaft k17 at the will of theoperator; Through the mechan ism' described shaft 14- is rotated andacts,

kvthrough arm 13 and link 12, to propel the knife-carrier 11 around theendless guideway 271, fixed tothe frame of the machine. This guideway 21is'inlplan of the same general,4

4sha e as the form ithin shaft 14`isa rod22 .xed at its lower endtofform A nd pivotally connected at its kupper end to a lever-23. Aswill be fclear, vthe form A and knife-carrier 11 may be raised by meansof lever 23 when the stock ist to beinsertedi'or withdrawn from the ma.

`chine,.and at such times the shaft '14 is free *tomo've endwisein gear15. A sprin 24 is provided for yieldin ly holding the orm A against theSteck wit the necessary pressure, and so that said form, together withthe knife;carrier, may be raised and, lowered when necessary. 'TheOperation vThe operator through lever 23 .raises'form A and theknife-carrier 11, inserts the stockbetween. form A and bed 3, andthen-lowers `form vA and the knife carrier 11. He then o crates lever 20and connects Wheel 178 with s aft 17 lthereby setting the machine inmo'- of the machine isfas follows:
